- All files and filesystems in Unix are arranged into one big directory

- Enabling this feature allows mount to use the '-o' loop options,

+ The mount command will detect you are trying to mount a file instead
+ of a block device, and transparently associate the file with a
+ loopback device. The umount command will also free that loopback
+ device.
+
+ You can still use the 'losetup' utility (to manually associate files
+ with loop devices) if you need to do something advanced, such as
+ specify an offset or cryptographic options to the loopback device.

+ Historically, Unix systems kept track of the currently mounted
+ partitions in the file "/etc/mtab". These days, the kernel exports
+ the list of currently mounted partitions in "/proc/mounts", rendering
+ the old mtab file obsolete. (In modern systems, /etc/mtab should be
+ a symlink to /proc/mounts.)
+
+ The only reason to have mount maintain an /etc/mtab file itself is if
+ your stripped-down embedded system does not have a /proc directory.
+ If you must use this, keep in mind it's inherently brittle (for
+ example a mount under chroot won't update it), can't handle modern
+ features like separate per-process filesystem namespaces, requires
+ that your /etc directory be writeable, tends to get easily confused
+ by --bind or --move mounts, won't update if you rename a directory
+ that contains a mount point, and so on. (In brief: avoid.)
+
+ About the only reason to use this is if you've removed /proc from
+ your kernel.
